This table defines how an input number is modified from its original form, depending on originating info (BG, NP), terminating info (BG, NP and optionally endpoint). The output type of number may also be specified set for optimization, if desired.
Number Modification Rules
Creating DNM Modification Rules based on Priority Level
DNM Modification rules are looked at in a very specific order. This order is maintained within the Number Modification library and is roughly as follows:
Getting Dialable Numbers
Get Dialable Number is used to provide a dialable display number to a subscriber endpoint or a non-subscriber endpoint. This API returns the 'dialable number' (formatted number) for an input number (i.e. the 'From' number) in the context of the endpoint or subscriber that will receive the dialable number (i.e. the 'To' number).
Dialable Number Optimization Logic
How to Add/Edit Display Number Modifications
This procedure describes how to create/edit Display Number Modifications table at the system wide or subscriber level. Enables the administrator to create records in the Display Number Modifications table. If an external gateway or B2BUA requires that the "calling party's display number" (e.g. number of the calling party) be changed to a specific format (Output Type Of Number) or if optimization is desired, an entry must be created for this in the modifications table. If no entry has been added by the administrator into this table, then the display number will pass unchanged. The Modifications table entries will apply to any number that is presented to any of the parties involved in a call, Therefore it applies to the alerting number, the busy number, the forwarding number, the transferring number, etc. As a word of caution, of course, if the administrator enters invalid data in this table, then incorrect display numbers will be presented.
